A Comprehensive Review of Stone Dust in Concrete: Mechanical Behavior, Durability, and Environmental Performance

“…As was observed for other stresses, studies have observed a decreasing trend in shear strength with higher SD contents, which can be attributed to the reduction in the void-filling potential [40] and the decrease in adhesion in the transition zone between particles [48] in concretes with levels of 75-90% replacement, contents that are beyond the percentages considered ideal [40,48,52].…”

“…As compared to natural fine aggregate, the stone-processing dust contains a higher amount of fine particles, and this is explained by the fact that it is a residual product of the mining industry due to the cutting, rolling, and explosions of the original stone massifs [118]. Besides the fact that the particles are more irregular [52], stone dust has higher water absorption characteristics, due to its high porosity and particle fineness and consequently a larger surface contact area when compared to NS [86]. Furthermore, the water absorption of the SD aggregates showed significant variation in values between the studies.…”

“…At certain levels of addition of SD, an improvement in tensile strength is observed, a property that begins to decrease with the increase in these levels, reaching values below the control mixture without addition [85]. [48] in concretes with levels of 75-90% replacement, contents that are beyond the percentages considered ideal [40,48,52].…”

“…In recent decades, the use of construction and demolition waste as coarse and fine aggregates has emerged as a proven sustainable solution [32,35,36]. Several studies have been conducted to evaluate the feasibility of recycling waste to produce sustainable concrete, such as granite and marble residues [37][38][39][40][41], stone dust [42][43][44][45][46][47][48][49], fly ash [42,50], limestone and quartz powder [50][51][52], jute fiber [53], ceramic waste [48], crumb rubber [54], rice husk ash [49], plastic wastes from recycled face masks [55,56], microplastics [57,58], EPS [59,60], and others [61][62][63][64].…”
